moles of oxygen: 1/2 x moles of water
= 1/2 x 7.8 = 3.9
Chemical equilibrium is a dynamic equilibrium that is affected by changes in temperature, concentration and pressure
<h3>What is chemical equilibrium?</h3>
Chemical equilibrium is a dynamic state in a chemical reaction in which the rate of forward reaction is equal to the rate of backward reaction.
For a reaction in equilibrium, the following factors affect equilibrium:
- temperature
- pressure
- concentration
The principle of chemical equilibrium states that in an isolated system in equilibrium, equilibrium will shift to annul any constraint applied in the system.
Therefore, chemical equilibrium is dynamic and is affected by temperature, concentration and pressure.

It's important for scientists to share their investigations so other scientists can learn from that one scientist's mistakes. Also, so that they can build on one another's successes.
In comparing two isotopes of the same element, the atomic number, stays the same.
Allow me to explain: The protons in an isotope ALWAYS stays the same, but the neutrons change. But, what's the atomic number made up of?
Protons, which means it won't change.
However, the atomic mass is made up of neutrons + protons, so only the atomic mass would change - not the atomic number.
Answer:
Option A. It has stayed the same.
Explanation:
To answer the question given above, we assumed:
Initial volume (V₁) = V
Initial temperature (T₁) = T
Initial pressure (P₁) = P
From the question given above, the following data were:
Final volume (V₂) = 2V
Final temperature (T₂) = 2T
Final pressure (P₂) =?
The final pressure of the gas can be obtained as follow:
P₁V₁/T₁ = P₂V₂/T₂
PV/T = P₂ × 2V / 2T
Cross multiply
P₂ × 2V × T = PV × 2T
Divide both side by 2V × T
P₂ = PV × 2T / 2V × T
P₂ = P
Thus, the final pressure is the same as the initial pressure.
Option A gives the correct answer to the question.
